Introducing the strongest coffee in the world

By Troy Frisby, Buzz60

Say hello to the world's strongest coffee.

Black Insomnia is newly available in America, and it has more than double the strength of Starbucks dark roast, depending on how you brew it, obviously.

After debuting in South Africa last June, it's finally available stateside. The brand blends Ugandan, Guatemalan, and Brazilian coffee beans for a hazelnut flavor.

The company suggests you drink Black Insomnia with "no sugar" and "less milk," calling the drink "a caffeine infused kick in the face to the tired, the old, and the mediocre."

While a shot of Black Insomnia is one thing, a single cup might contain more than 700 mg of caffeine, which would exceed the daily FDA recommendation of 400 mg.

A researcher at Johns Hopkins School of Medicine tells CNN doubling your caffeine could potentially lead to jitteriness, trouble sleeping and, most seriously, cardiac arrhythmia.

But people seem to love it. Black Insomnia costs $19 a pound, and the companies selling between five and six tons of it each month.

Black Insomnia is competing against a similar brand of coffee called Death Wish, which uses a skull and crossbones as its logo.

When did drinking coffee become an extreme sport?
